' v,.tplilication filent ,and useful Improvements in Automobile theel-Rims, ot' which the following is a My invention .relates to the improvement oit autoniobile wheel runs of that class which are provided with what is known as quick detachable means and the obJects ot my invention are to provide a wheel rim con struction of this` class embodying improved moans for securing` a tire .in connection therewithand tor locking the tire retaining member in engagement with the rim; to providcan improved rim and tire retaining member of such construction and arrangement of parts as to admit ot' said retaining member being quickly detached from or attached to the rim and to provide `other improvements the details of construction of' which willbc more fully pointed out hereinat'ter. These objects I accomplish in the manner illustrated in the accompartying` drawing, in whichlifigure l fs a side elevation. ot the atl-- jaet'rnt end portions ol the tire retaining meniber, Fig. 2 is a similar view oi a portion Oi the wheel elly and rim, showing the adjoining end portions of the tire re taining, member in connection therewith, Fig. 3 is a plan view of a portion of the outer margin el the rim, Fig. 4t is a View in elevation of an automobile wheel having my improved construction, Fig. 5 is an enlarged transverse section through `the wheel rim and telly, Fig. 6 is a detail view in perspective oit portions ot' the wheelV rim, :telly and tire. and, Fig. 7 .is a side elevation ol? that portion ot thc retaining member in which located a connecting' hinge.

Similar numerals refer to similar parts throughout. the. several views.

l represents the circular telly of an automobile wheel and 2 the metallic rim, which is carried on the periphery of said telly. This rim is in the nature of a llat band, the inner marginal portion of which is curved upward and inward into hook form, as shown at 2 to engage the usual laterally projectingr base portion 3 of a pneumatic.,

or channeled member 2",.thc upper side of the outer portion of which is in horizontal alinemont with the Lipper side of the body ol the rim. In the construction of the rim member 2b, I form therethrough at a suitable point -an elongated opening or mor- Lise 4.

5 and tl represent respectively half circular or semi-ring members, two oi the adjacent ends ot which are suitably hinged one to the other as indicated at 7 in Fig. 7 of the drawing. The remaining ends ot" the members 5 and t3 lwhich are adapted to bc lnfought into contact with each other to result in the formation of a tire retainine ring, are -l'm'med'with inclined or diagonal end surl'aces, as shown. 'Qld-ach of these rctaining or ringl members has its upper and outwardly prtritctinpn portion, formed with a continuous inner side curved recess 5, which imparts -a hook form thereto. The lower and narrower portions of the members 5 and. (3, are in thc nature of half .round extensions oi'v the upper portions or the bodies thereof, these rounded lower portions being' indicated respectively at 8 and t). uBeneath its 'lree end the section 5 is formed with af downwardly extendingl squared eXtension'lO which has a radial `screw or threaded termination 10ft. Beneath the correspondinnl end ot' the section t5 is likewise provided a downwardly extending angular lug or projection 1l. the lower horizontal arm of which is indicated at 1].

In utilizing my device, a tire, a portion of which is indicated at 3, is slipped over or upon the body of the rim 2 in the usual manner. one o'l' the rounded heel projet-.tions 25 oil the tire engaging the recess ot the rim hook 2, The tire being` in this position, the sectional ring 5-t has its inner rounded portions S and il seated in the channel ot the rim member ifin the manner indicated more clearly in Figs. 3 and G of the drawing'. ln thus seating;n the sectional ring, it will be understood that the angular lug 1l is first inserted downwardly through the opening' 'l, alter which 4the section G is moved until the projecting terminal portion ll of the lug l1 is in engagement with the iinderside ot the channeled member 2b of ilo at one side of the member 1l and adjacent thereto. This being accomplished and the inclined ends of the ring sections having been brought together, a nut such as is indicated at l2, is screwed on to the threaded extension 10a of the projection 10 until said nut is in contact with the underside of said projection l0 and with. the underside of a shoulder 1lb of the lug 1l. By thus securing thevring sections 5 and G in the groove or channel of the member 2b, it is obvious that the outer heel 3a of the tire base, will be properly embraced in the recess 5 and the tire held firmly between the parts 5 and 6 and 2a.

itis obvious that a tire held in the man` ner described, may be quickly detached from the rim by withdrawing the nut l2, raising the end of the member 5 upward until its lug lO and threaded extension are out of engagement with the member 2", sliding the member 6 in its bearing until its projecting `portion l1a is out of engagement with the rim member 2l and moving the sections 5l and 6 outward away 'from each other and out of the channel 2b.

It will readily be understood that the operation of adjusting the sectional locking or retainingT ring to its locked position and the removal of the same from the channel, will be greatly facilitated by the formation of the hinged joint? in said sectional ring at a point diametrically opposite the point of connection with the rim.

From the construction and operation described, itis obvious that by the use of the rim and tire retaining ring herein described,

la tire may be readily detached from an aureadily secured jects of the invention, but while the elements shown and described are Well adapted to serve the purposes for which they are intended, itis to be understood that the invention is not limited to the precise construction set forth, but includes Within its purview such changesl as may be made within the scope of the appended claim.

What I claim, is: j

An automobile wheel rim comprising a flat metal band, a peripheral hook-shaped liange on one edge of said band, an integral peripheral iiange of U-shape in cross-section on its other edge and having a'slot therein, a removable split, hook-shaped member fitting in said last named flange, an L-shaped lhook on one end of said member constructed to engage one wall ofl said slot, a shoulder on said L-shaped hook, a complemental shoulder on the other end of said split hook-v shaped member and having a threaded extension, the meeting ends of said split hook.

shaped member being beveled, and a nut for said threaded extensin` and adapted to bear against said two shoulders to bring the free ends of said split hook-shapedmember in abutting relation.

In testimony whereof I aiiix my signature in presence of two Witnesses.
